Test Weight Adjustment Calculator
Estimate elevator dock deduction and revenue impact based on grain test weight.
Inputs
How It Works
Pounds Under = Standard − Actual
Dock per Bushel = Pounds Under × Dock Rate
Total Dock = Dock per Bushel × Bushels
FAQ
What is standard test weight for corn?
Standard test weight for corn is typically 56 lb per bushel.
Why does test weight matter?
Lower test weight grain may result in elevator dockage and reduced sale price.

Yes. Dock rates and thresholds vary by location and buyer policy.
About Test Weight Adjustments
Test weight measures the density of grain and is expressed in pounds per bushel. Grain below the standard test weight may receive a dock at the elevator, reducing the effective sale price per bushel.
Low test weight can result from weather stress, disease, poor grain fill, or harvest timing. Even small differences below standard can significantly impact revenue across large volumes of grain.
Understanding potential dock adjustments helps producers evaluate marketing decisions and determine whether storage, blending, or alternative marketing strategies may improve final net revenue.
